Sounds uncomfortable. One thing you can try is to do reverse ear pops.. My ENT taught me how and to do it, you hold your nose and gently blow and your ears will pop. I do it a few times when I feel that clogged, full feeling or muffled hearing as I am prone to Eustachian tube dysfunction. I am to sure what the origin of your issue is though. Do you have any issue of wax buildup? That also can cause that same type of thing. Debrox bought at the drug store removes wax from ears. So, give those two things a try and if it continues, see your doctor.
